Evaluating the Diagnostic Accuracy of Point-of-Care Ultrasound in Acute Abdominal Pain in the Emergency Setting.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPoint-of-care ultrasound (POCUS) is increasingly recognized as a valuable diagnostic tool in emergency departments, particularly for evaluating non-traumatic acute abdominal pain. This study assessed the diagnostic accuracy of POCUS in identifying the most common causes of acute abdominal pain, i.e., appendicitis, cholecystitis, bowel obstruction, and renal colic, presenting in an emergency setting. METHODOLOGY: This prospective observational study was conducted over 12 months at Mardan Medical Complex and District Headquarters (DHQ) Teaching Hospital, Gujranwala, Pakistan. A total of 180 adult patients (≥18 years) presenting with non-traumatic acute abdominal pain were enrolled using convenience sampling. POCUS was performed by trained emergency physicians in accordance with American College of Emergency Physicians (ACEP) guidelines. Final diagnoses were confirmed through radiological, surgical, or clinical outcomes. Data were analyzed using SPSS version 26.0 (IBM Corp., Armonk, NY). Statistical measures included sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy.
resultsThe mean age of the patients was 39.5 ± 13.6 years (range: 18-80 years), with a slightly higher male predominance: 94 (52.2%) males and 86 (47.8%) females. The most common final diagnoses were appendicitis (44, 24.4%), renal colic (34, 18.9%), cholecystitis (30, 16.7%), and bowel obstruction (28, 15.6%). POCUS correctly identified the pathology in 150 (83.3%) cases. Condition-specific diagnostic accuracies were appendicitis at 92.2%, cholecystitis at 93.7%, bowel obstruction at 94.2%, and renal colic at 93.9%. Cases with nonspecific or unidentifiable abdominal pain were grouped under "Other" and not stratified further. Gender-based accuracy was comparable, with 79 (84.0%) correct diagnoses in males and 71 (82.6%) in females.
conclusionPOCUS demonstrated high diagnostic accuracy for four of the most common abdominal emergencies, i.e., appendicitis, cholecystitis, bowel obstruction, and renal colic, and showed consistent performance across genders. While these findings support the role of POCUS as a valuable tool in emergency settings, particularly in resource-constrained environments, they should be interpreted within the study's scope. Broader generalization to all causes of abdominal pain requires further research with larger, more diverse patient populations and long-term follow-up.
